A SIMPLE ERROR-CORRECTION METHOD FOR 2-PORT TRANSMISSION PARAMETER MEASUREMENT

This letter presents a simple error correction method for two-port tra nsmission parameter measurement. The method requires measuring only tw o nonreflecting transmission lines instead of a complete set of calibr ation standards (at least three) for error correction, It does not nee d an explicit solution of error coefficients, These two features make it simpler than any other methods. Error-corrected measurement results of a CPW discontinuity using the new method and the TRL method are in good agreement. The new method is useful in characterizing well-match ed two-port devices or those whose reflection parameters are of little interest.
